MATERIAL-HANDLING MECHANISM.

Patented Oct. 18, 1910. Serial No. 482,584.

To all whom it may concern:

Be it known that I, HARRY ZiMMnnMAN, a citizen of the United States, residing at Fremont, Sandusky county, Ohio, have invented new and useful M'aterialJ-landling Mechanism, of which the following is a specilication.

This invention relates to the handling of material.

This invention has utility when embodied in a measuring*cutting-counting machine, being especially adapted for use in connection with material put up in bolts, spools r rolls, and satisfactorily handling the material even though the material is easily stretched or distorted, as knit tubular stock. The material can be handled for cutting and the mechanism effective not only in measuring off constant lengths to be out, but also in measuring off constant predetermined numbers of the cut portions.

Referring` to the drawings: Figure 1 is a side elevation, with parts broken away of an embodiment of the invention in a material handling mechanism; Fig. 2 is a detail view in elevation of a portion of the pay out device and supply carrier support; Fig. 3 is an elevation, with parts broken away of the supply carrier sleeve and one disk; Fig. 4 is a similar view of the second disk of the supply carrier, which with the showing of Fig. 3 completes the supply carrier reel; Fig. 5 is a fragmentary elevation of the tension device and stop motion trip features; Fig. (i is a perspective view showing a portion of the feed device, reverse travel lock and material holding device; Fig'. 7 is a fragmentary showing in elevation from the opposite side of the mechanism from the view of Fig. 1; and Fig. 8 is an elevation with parts removed and broken away and looking from the right of Fig. 1.

The mechanism is mounted on the base 1, carrying the bracket or support 2 for the supply carrier and portion of pay out device. In the bracket 2 is mounted the spindle 3 over which may slip the sleeve 4 fixed to one of the disks 5 of the supply carrier. The spindle 3 has a groove G therein, While sleeve 4 has an opposing` groove 7, so that when sleeve 4 is pressed over spindle 3, the

spring ring 8 will lock the sleeve and spindle together but permit of free rotation of the sleeve. The sleeve is provided with a plurality of grooves 9 into any one of which may lock the pair of spring thrown levers 10 to hold the second disk 5 in such relation to the first disk 5 as the roll of material permits. The outwardly extending lugs 11 allow of ready removal of this second disk 5 at any time it is desired to recharge the carrier. Vith a plurality of reels or supply carriers at hand, a more rapid operation may result by complete removal of the reel from spindle 3 and replacement by another reel already charged.

The material 12, in passing from the carrier, travels over a feed device or roller 13 of the pay out device, which roller is mounted on the reciprocable arm 14 having pivotal connection 15 with the bracket 2. This arm 14 has slot 16 with which rod 17 may be locked to give roller 13 such reciproeation by the travel of rod 17 as to pay out the material as desired. The rod 17 is actuated by eccentric 18 (Fig. 7) on shaft 19, which shaft 19 is driven through worm wheel 20, from worm 21, having fast therewith the pulley 22, connected by belt 23 to pulley 24 on the eountershaft 25 in bracket 2G on the base 1. On this shaft 25 is the fast or fixed pulley 27 adjacent the loose pulley 28 driven by the continuous driving belt 29.

The material 12, paid out by the reciprocation of arm 14, passes from roller 13 over rollers 30 and 31, being affected therebetween by the pivoted tension device 32 having thereon the adjustable weight 33, so that there is a constant drag on the material 12 in passing from roller 31, placing the material under uniform tension, to insure evenness in length of the cuttings as well as give the material more of a firmness in feeding, instead of leaving it flimsy. These rollers 30, 31 and tension device 32 are mounted in the bracket 34 carried by the base or sup,- port 1.

The material passing from the roller 31 goes under the reverse travel lock 35 (Fig. 6), which is a pivotally mounted member having its teeth directed along the line of travel of the material, so that action of the tension device 32 or of the pay out device` will at once work on the reel or supply carrier for the teeth will immediately engage to hold the material 12 as backward or reverse travel commences. The lock 35 is provided with the cam face 3G which is engaged minus for discharge over the receiver 43 rotation of shaft 19 feeds forward a length by the spring 37 to yieldably hold the lock il in engagement with the material. y

Mounted on the shaft 38- at the top of the support 1 is the arm 39 normally held I down by the spring 40 so that its double row of holding teeth 41 may firmly engage the material which has passed the reverse travel lock 35. The material 12 in traveling from lock 35 and under holding device 41 moves along the way 42 which has its terinto which the cut portions of the material are counted by the mechanism.

The feeding of the material passing the reverse travel lock 35 is brought about by the roughed segment 44 of the feed device, which by continuous rotation produces an intermittent feeding of the material under the holding device 41.

Fast with shaft 38 is arm 45 having roller 46 traveling on cam 47 mounted on shaft 19, so that the holding device 41 is released to permit the feed device 44 to be effective, and as soon as the feeding operation stops, the cam 47 permits the spring 40 to reset the holding device 41, while the rotary cutter 48 is reciprocated between the portions of the holding device to sever a measured length of the material 12.

The reciprocation of cutter 48 is eifected by a rocking of the arm 49 carrying the cutter (Figs. 7 and 8). This rocking of arm 49 is through the link 50 connected to arm 51 of a rock shaft having oppositely extending arm 52 with roller 53 engaging the cam 54 on the side of cam disk 47.

F ixed with the rotary critter or knife 48 is the pulley 55 (Figs. 1 and 8) connected by cross belt 56 with the pulley 57 fixed on shaft 25, so that in the running of the mechanism the cutter 48 is constantly rotating.

To hold the cutter 48 normally out of the line of travel of the material 12 along the way 42, the spring 58 is provided, the action of which is overcome by the cam 54. In order to avoid concussion due to the quick action of the spring 58 when running the mechanism at a high rate of speed, there is provided the buffer plunger 59 with which the arm 49 of the cutter may come in contact and have its throw 'yieldingly taken care of.

Eccentrically mounted on shaft 19 is the pawl 60 (Fig. 7) normally held in position by the spring 61, while the dog 62 with the pawl 60 contacts the ratchet wheel 63. By this device there is a counting action, each of the material to be cut, while simultane-1 ously there is a paying out of material through action of rod 17, and further a rotation by one tooth of ratchet wheel 63 on its shaft 64. Mounted on this ratchet wheel 63 is the cam 65 contacted by roller 66 on rock arm 67 of rock shaft 68 (Fig. 8). This shaft 68 has an arm 69 (Fig. 1) connected to spring 70, so that roller 66 is normally held against the cam 65. The shaft 68 also has the arm 71 connected by link 72 to arm 73 of rock shaft 74. This rock shaft 74 has an arm 75 connected by link 76 with a rock shaft 77. An additional arm 78 on rock shaft 74 is connected by link 79 to cranked rock shaft 80, while a fourth arm 81 on rock shaft 74 is connected by link 82 with the cranked rock shaft 83. Connected to be rocked with the cranked shafts 77 and 83 are the receiver bottom sections 84, while connected to be rocked with the cranked shafts 74 and 8() are the receiver bottom sections 85. )While the receiver 43 is not shown in Fig. 8, the bottoms 84 are shown as closed and the bottoms 85 as open. In Fig. 1the relation of the bottoms is shown reversed, 84 open and 85 closed.

The material 12 in passing from roller 31 to lock device passes under the weighted arm 86 of the stop motion (Figs. 1 and This arm 86 has an angular extension 87 pivoted on the frame 88, so that as the material supply fails and the weight 86 falls, it will cause the wing 89 on the extension 87 to move into the line of travel of the enlargement 90 carried by reciprocable rod 17. The frame 88 is carried by the movable bar 91 which has a fork or pair of lingers 92 between which the material 12 passes to properly locate the weighted arm as to the material. Obstructions in material engage fingers 92 to operate the stop motion. The remote portion of the movable bar 91 is slidable in the way 93 carried by the receiver 43. This bar 91 is connected to hand lever 94 pivoted at 95 to the receiver supporting frame. The hand lever 94 has a belt shifting fork 96 to engage the continuously driving belt 29, so that when enlargement 90 on the rod 17 is effective to move the bar 91 the belt 29 is shifted from the fast pulley 27 to the loose pulley 28 and the mechanism is stopped.

In regular operation the mechanism needs no further attention than keeping the supply carrier charged and removing the counted quantities of cut material.

Starting up the charged mechanism, with the material 12 led therethrough as indicated, cutter 48 is rotating and shaft 19 is driving the variously interconnected devices which so mutually coact in performing their cycles of operation which lead up to the unitary result that the timing of the intermittent actions brings about a continuity and regularity combined with great speed which means a considerable saving in labor as well as accuracy as to result attained. Shaft 19, through the pay out arm 14 to which it is connected by eccentric 18 and rod 17 withdraws material from the carrier reel sleeve 4, which the feed device 44 carries forward under the holding device 41 for the cutter 4S to act upon in measured lengths of no variation, for the tension device 32 places a constant drag on the material, While lock 35 prevents backward travel. The cut length of material in being pushed by the holder 41 with the next length of material to be cut, is deflected toward the receiver 43 by the pivoted hood 97, mounted above the Way 42. This shoving of the material l2 forward occurs after knife 48 is removed from the line of Way 42. Coineident with the travel of the cutter 48 through the material and back out of the Way, there is the operation of the pay out device, the feeding of the next length of material to be cut, the release and setting of the material holding device, the counting up of the cuts made, and after a predetermined number of cuts are made, the dumping of the receiver 43 by opening of bottoms S5 and closing of bottoms 84, a little later followed by bottoms 84 dumping upon bottoms 85 for a subsequent repetition of the operation.

Cam 47, Fig. 7, through crank 45 lifts holder 4l to permit the next length of material to be fed by segment 44. As the feeding action ceases, holder 4l at once engages the material by force of spring 40 as cam 47 again presents smaller radius to cam roller 4G. lVhile roller 46 is traveling over this smaller radius of cam 47, the cam 54 (Figs. 7, 8) through rock arms 52, 5l and link 50, oscillates link 49 carrying the rotary cutter 48, across the held material to sever the measured length thereof. As soon as roller 53 passes over cam 54, spring 5S retracts the cutter to permit the succeeding length of material to be fed as the enlarged portion of cam 47 lifts the holder 4l.

Each rotation of shaft l), besides causing the feeding and cutting of a length of material, actuates the pay out device, and further counts one tooth on the Wheel 63. Each rotation of the counter Wheel 63 effects a dumping from the receiver of a predetermined quantity of cut material. This dumping of the predetermined number of cuttings is effected by cam G5, rock crank G7, rock shaft 68, arm 7l and link 72. fhile roller 66 is traveling on the larger radius portion of cam 65, the bottom sections 85 of receiver 43 are in holding' position and sections 84 are in open position. lvVhen the roller 66 reaches the smaller radius of cam 65, to which cam it is held by spring 70 (Fig. l) engaging arm 69 of rock shaft GS, the movement of link 7 2 resulting from this rocking of shaft 68, causes links 76 and 82 to close the bot-tom sections 84 and dump or open the bottom sections S5 to discharge a predetermined number of cut portions of material. The bottom sections 84 catch the cuttings form operation While this discharge is taking place. The continued operation causes roller (S6 to again reach larger radius portion of cam (55, when bottom sections 85 are closed and sections 84 opened, the latter discharging upon the former. The coutinued rotation of cam (35 causes repetitions of this counting operation. As before recited, an exhausting of the supply of material, will at once result in the dropping of arm SG and stopping of the mechanism by shifting the belt 29.
